【Abstract】 In the application of reyleigh surface wave on the testing of subgrade reinforced through grouting, the wave speed isoline cross-section can be used to detect the potential weakness position so as to make a macro-evaluation in the three-dimensional space on the effect of subgrade reinforced through grouting, on the other hand combining with several times dynamic sounding, subgrade support can be indirectly calculated. from engineering case, stress has been given to the research on the macro-evaluation on the effect of the reinforced subgrade in engineering practice as well as on the sounding blow count and sampling problems in the regression analysis of wave speed.更多还原
